gget

快速 CLI/Python 查詢,可存取 20 多個生物資訊資料庫,用於基因資訊、BLAST/BLAT、病毒序列、AlphaFold 結構、富集分析、OpenTargets、COSMIC、CELLxGENE 及 8cube 小鼠特異性/表現資料。最適合互動探索與簡單查詢;批次處理或進階 BLAST 請用 biopython;多資料庫 Python 工作流程請用 bioservices。

gget 是什麼?

gget 是一個命令列生物資訊工具及 Python 套件,提供統一的介面查詢超過 20 個基因體資料庫與分析方法,涵蓋基因參考資訊、序列比對、蛋白質結構、病毒序列、表現資料、疾病關聯以及小鼠組織/細胞特異性指標。大部分模組可同時作為命令列工具與 Python 函數使用,輸出格式包括 JSON、CSV 與 DataFrame。該技能支援多種常見工作流程,如基因特徵分析、結構比較、表現與富集分析、疾病與藥物關聯等,並提供詳細的參考文件(module_reference.md、database_info.md、workflows.md)以指導使用者操作。gget 特別適合互動式探索與快速擷取,但對於大規模批次處理建議使用 biopython 或 bioservices。使用者應注意資料庫結構可能變更,建議在可重現環境中鎖定版本(如 gget==0.30.5),並遵循最佳實踐以避免 API 速率限制與依賴衝突。

gget 是做什麼的?

概覽

gget 是一個命令列生物資訊工具及 Python 套件,提供統一的介面查詢超過 20 個基因體資料庫與分析方法。您可以透過一致的介面查詢基因資訊、序列分析、蛋白質結構、病毒序列、表現資料、疾病關聯,以及小鼠組織/細胞特異性指標。大部分 gget 模組既可作為命令列工具,也可作為 Python 函數使用。

重要提示:gget 查詢的資料庫會持續更新,有時會改變其結構。此處指南適用於 gget 0.30.5(截至 2026-06-07 的 PyPI 最新版本)。為確保可重現性,請鎖定 gget==0.30.5;若上游資料庫轉接器失效,請在檢查版本說明後更新 gget。

安裝

請在乾淨的虛擬環境中安裝 gget,以避免衝突:

# 針對此技能的可重現安裝
uv venv .venv
source .venv/bin/activate
uv pip install "gget==0.30.5"

# 在 Python/Jupyter 中
import gget

快速入門

所有模組的基本使用模式:

# 命令列
gget <module> [arguments] [options]

# Python
gget.module(arguments, options)

大多數模組會回傳:

  • 命令列:JSON(預設)或 CSV(加上 -csv 旗標)
  • Python:DataFrame 或字典

跨模組的常見旗標:

  • -o/--out:將結果儲存至檔案
  • -q/--quiet:隱藏進度資訊
  • -csv:回傳 CSV 格式(僅限命令列)

Python 的參數名稱通常與長版 CLI 選項相符,但不含前導破折號。例如 --census_version 變成 census_version=...。請使用 gget <module> --help 查閱確切的目前簽章。

模組分類

gget 提供六個類別共 23 個模組。每個模組的參數、CLI 與 Python 範例以及回傳形狀,請參閱 references/module_catalog.md;更完整的每個參數文件請參閱 references/module_reference.md。

類別模組
1. 參考資訊與基因資訊ref(Ensembl 參考下載)、search(基因搜尋)、info(基因/轉錄本詳細資訊)、seq(核苷酸與蛋白質序列)
2. 序列分析與比對blast、blat、muscle(多重序列比對)、diamond(局部比對)
3. 結構與蛋白質分析pdb(結構與後設資料)、alphafold(結構預測)、elm(線性模體)
4. 表現與疾病資料archs4(相關性、組織表現)、cellxgene(單細胞)、enrichr(富集分析)、bgee(直系同源與表現)、opentargets(疾病與藥物)、cbio(癌症基因體學)、cosmic(突變)
5. 病毒與小鼠特異性virus(病毒序列)、8cube(小鼠特異性與表現)
6. 其他工具mutate(突變序列)、gpt(文字生成)、setup(安裝模組依賴)

部分模組在首次使用前需要執行一次性的 gget setup(alphafold、elm、cellxgene),而 cosmic 會提示輸入 COSMIC 憑證以下載其資料庫。

常見工作流程

多模組管線範例——基因特徵分析、結構比較、表現與富集分析、疾病與藥物關聯、直系同源比較,以及為 kallisto 或序列比對準備參考檔案——請參閱 references/common_workflows.md,較長版本請參閱 references/workflows.md。

最佳實踐

資料擷取

  • 使用 --limit 控制大型查詢的結果數量
  • 使用 -o/--out 儲存結果以確保可重現性
  • 檢查資料庫版本/釋出號碼,確保跨分析的一致性
  • 在正式腳本中使用 --quiet 以減少輸出

序列分析

  • 對於 BLAST/BLAT,先使用預設參數,再調整敏感度
  • 使用 gget diamond 搭配 --threads 以加速局部比對
  • 使用 --diamond_db 儲存 DIAMOND 資料庫,以便重複查詢
  • 對於多重序列比對,處理大型資料集時使用 -s5/--super5

表現與疾病資料

  • 在 cellxgene 中,基因符號區分大小寫(例如 'PAX7' 與 'Pax7')
  • 首次使用 alphafold、cellxgene、elm、gpt 前,請先執行 gget setup
  • 對於富集分析,可使用資料庫捷徑以方便操作
  • 使用 -dd 快取 cBioPortal 資料,避免重複下載
  • 對於 OpenTargets,在撰寫篩選條件前請先檢查回傳的欄位名稱;gget 0.30.5 遵循新版 OpenTargets API 架構

結構預測

  • AlphaFold 多聚體預測:使用 -mr 20 以獲得較高準確度
  • 使用 -r 旗標對最終結構進行 AMBER 鬆弛
  • 在 Python 中以 plot=True 視覺化結果
  • 在執行 AlphaFold 預測前,請先檢查 PDB 資料庫

病毒資料

  • 在請求大型病毒資料集前,使用 gget virus 搭配限制性篩選條件
  • 將 command_summary.txt 與下游結果一同保存,以確保可重現性並能在部分下載後復原
  • 使用 --baseline 與 --merge-results 恢復中斷的病毒後設資料/序列下載

錯誤處理

  • 資料庫結構會變更;當轉接器失效時,請檢查上游版本說明,並明確鎖定較新的修復版本
  • 為確保可重現環境,請鎖定已知良好的版本:uv pip install "gget==0.30.5"
  • 使用 gget info 時,一次最多處理約 1000 個 Ensembl ID
  • 對於大規模分析,請對 API 查詢實施速率限制
  • 使用虛擬環境以避免依賴衝突
  • 將 COSMIC 與 OpenAI 憑證保存在指定的環境變數或互動提示中;切勿將真實憑證寫入範例、筆記本或日誌中

輸出格式

命令列

  • 預設:JSON
  • CSV:加上 -csv 旗標
  • FASTA:gget seq、gget mutate
  • PDB:gget pdb、gget alphafold
  • PNG:gget cbio plot
  • FASTA/CSV/JSONL 資料夾:gget virus

Python

  • 預設:DataFrame 或字典
  • JSON:加上 json=True 參數
  • 儲存至檔案:加上 save=True 或指定 out="filename"
  • AnnData:gget cellxgene
  • DataFrame/JSON:gget 8cube specificity、psi_block、expression

Use when the user mentions AlphaGenome, AlphaGenome Atlas, AVI or AlphaGenome Variant Impact, DeepMind variant effect prediction, or wants to prioritise or mechanistically interpret non-coding, regulatory, splicing, enhancer, promoter, or chromatin-accessibility effects of SNVs from a VCF, credible set, or region. Research use only; not a clinical tool.

analytical-method-validation

Plan, execute, and document validation, verification, and transfer of analytical procedures under the governing framework - ICH Q2(R2) and Q14, USP <1220>/<1225>/<1226>, ICH M10 bioanalytical, CLSI EP, or ISO/IEC 17025. Use for HPLC, LC-MS/MS, GC, CE, ICP-MS, dissolution, qNMR, qPCR, NIR, and ligand binding or cell-based assays whenever the question is whether a procedure is fit for its intended purpose. Triggers include

anndata

Data structure for annotated matrices in single-cell analysis. Use when working with .h5ad files or integrating with the scverse ecosystem. This is the data format skill—for analysis workflows use scanpy; for probabilistic models use scvi-tools; for population-scale queries use cellxgene-census.

arbor

Autonomously improve a real artifact (code, training recipe, agent harness, data pipeline, prompt) against an objective and an evaluator, using Hypothesis Tree Refinement (HTR) from the Arbor paper. Use this whenever someone wants to iteratively optimize something over many experiments without overfitting — e.g.

arboreto

Infer gene regulatory networks (GRNs) from gene expression data using scalable algorithms (GRNBoost2, GENIE3). Use when analyzing transcriptomics data (bulk RNA-seq, single-cell RNA-seq) to identify transcription factor-target gene relationships and regulatory interactions. Supports distributed computation for large-scale datasets.

bgpt-paper-search

Search scientific papers and retrieve structured experimental data extracted from full-text studies via the BGPT MCP server. Returns 25+ fields per paper including methods, results, sample sizes, quality scores, and conclusions. Use for literature reviews, evidence synthesis, and finding experimental details not available in abstracts alone.

biopython

Comprehensive molecular biology toolkit. Use for sequence manipulation, file parsing (FASTA/GenBank/PDB), phylogenetics, and programmatic NCBI/PubMed access (Bio.Entrez). Best for batch processing, custom bioinformatics pipelines, BLAST automation. For quick lookups use gget; for multi-service integration use bioservices.

bioservices

Unified Python interface to 40+ bioinformatics services. Use when querying multiple databases (UniProt, KEGG, ChEMBL, Reactome) in a single workflow with consistent API. Best for cross-database analysis, ID mapping across services. For quick single-database lookups use gget; for sequence/file manipulation use biopython.

bulk-rnaseq

End-to-end bulk RNA-seq orchestrator — takes raw FASTQ reads through QC and trimming (FastQC, fastp/Trim Galore), alignment and quantification (STAR, Salmon, featureCounts), assembles a gene-level counts matrix, then hands off to differential expression (pydeseq2), pathway/GSEA enrichment (pathway-enrichment), and publication figures (scientific-visualization). Use whenever the user has bulk RNA-seq reads or quant output and wants a complete, reproducible differential-expression workflow — e.g.

cellxgene-census

Query the CZ CELLxGENE Census programmatically for versioned public single-cell and spatial transcriptomics data. Use when you need population-scale cell metadata, gene expression slices, Census summary counts, source H5AD URIs/downloads, embeddings, spatial Census data, or reference atlas comparisons across organisms, tissues, diseases, assays, and cell types. For analyzing your own local single-cell data use scanpy, anndata, or scvi-tools.

cirq

Google quantum computing framework. Use when targeting Google Quantum AI hardware, designing noise-aware circuits, or running quantum characterization experiments. Best for Google hardware, noise modeling, and low-level circuit design. For IBM hardware use qiskit; for quantum ML with autodiff use pennylane; for physics simulations use qutip.

citation-management

Comprehensive citation management for academic research. Search OpenAlex, PubMed, and Google Scholar for papers, extract accurate metadata, validate citations, and generate properly formatted BibTeX entries. This skill should be used when you need to find papers, verify citation information, convert DOIs to BibTeX, or ensure reference accuracy in scientific writing.

clinical-decision-support

Prepare and validate research-only clinical decision-support evaluation, evidence-profile, cohort, survival, biomarker/model, privacy, and governance artifacts. Use for aggregate or synthetic research documentation and traceability—not patient care or live clinical operation.

clinical-reports

Create safety-bounded draft structures and run local deterministic checks for clinical case, diagnostic, trial, safety, and aggregate research reports. Use only with synthetic, de-identified, or aggregate inputs and verified source-fact manifests; every output requires qualified review.
